Baume& Mercier William Baume Ultra Thin Limited Edition

Ultra-thin watches have always been synonymous with superior elegance and extreme technical sophistication. Baume & Mercier began to specialize in ultra-thin watches from 1920 onwards, and in 1965 the brand caused a sensation with the thinnest self-winding calendar watch of its era. Baume & Mercier is now offering a new expression of its expertise in this field with this new William Baume Ultra-Thin model.

It differs from the previous version by three new features. The WB-UT002 movement manufactured by Valfleurier for Baume & Mercier is even more efficient, endowed with a power reserve amounting to 60 hours compared with 40 hours for the previous model.

The watch is also 0.4 mm thicker while nonetheless remaining ultra-thin with a 6.2 mm profile. The case-back is now open to reveal the mechanical hand-wound movement, admirably adorned with “Côtes de Genève” on the mainplate and bridges, along with blued steel screws. However, this new edition retains its silvered dial with “Vieux Panier” guilloché décor, its elegant “javelin” shaped hands and its hand-stitched chestnut brown strap. Its XL 41 mm case is crafted in 18K red gold. Limited, numbered edition of 179 watches.
